The 21-year-old pop singer gave rapper French Montana a $150,000 gold chain as a birthday gift in November after the two became friends in the studio.

But the ex of Khloé Kardashian added $90,000 in diamonds for an extra layer of spectacular bling to his necklace, as reported by TMZ.

French shared an Instagram snapshot on Friday of the upgraded necklace as he wrote: ‘Shout out to my bro @justinbieber for the bday gift and s/o to @iceman_nick for the details‼’

Bieber and Montana worked on their single together, Why You Mad (Infinity Remix) with Mariah Carey and T.I. last summer.

The pair became close friends since then and the Love Yourself hit-maker gifted French for his 31st birthday with the expensive jewelry.
